Embodiment 1
[0023] A coal mine heavy metal polluted soil improver, comprising the following raw materials in parts by weight: 50 parts of humus, 50 parts of fly ash, 20 parts of yeast cells embedded in silica gel, and 0.3 parts of mixed fatty alcohol; wherein the yeast is embedded in silica gel The bacteria were prepared by the following method: first, the rhodotorula was embedded in calcium alginate, then the calcium alginate-yeast strain was embedded in the silica gel matrix through the silica gel sol-gel method, and finally the silica gel was placed in the In the soluble citrate solution, the silica gel-embedded Rhodotorula thallus was obtained. The components of the above soil conditioner are simply mechanically mixed to obtain the soil conditioner.
[0024] The present embodiment also provides a method for applying a soil conditioner polluted by heavy metals in coal mines, comprising the following steps:
[0025] Firstly, the polluted soil around the coal mine will be plowed for the...
